EMIL I-IERZ, OF NEW YORK, N. Y.

TRAN SOM-LIFTER;

SPECIFICATION forming part of Letters latent No. 437,115, datedSeptember 23, 1890. Application filed July 8, 1890- Serial No. 358,116.(No model.)

To all whom it may concern:

Be it known that I, EMIL HERZ, of the city, county, and State of NewYork, have invented a new and Improved Device for Manipulating Doors andWindows, of which the following is a full, clear, and exact description.

My invention is an improvement in means for operating and locking doorsand windows that are hinged or pivoted.

The main features of the apparatus I employ are not new, but myinvention is embodied in the construction and combination of certainparts, as hereinafter described.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in both the figures.

Figure 1 is a front view of the improvement as applied in a closedposition; and Fig. 2 is a sectional plan view of the same on the line onm of Fig. 1, with the device in an open position.

The improved device is provided with a shaft A, arranged vertically andmounted to turn and to slide in brackets B and O, secured one above theother on the door-casing. On the lower end of the shaft A is secured ahandle D, and at the upper end of the said shaft is fastened an arm E,pivotally connect ed by a link F with an arm or bracket G, fastened tothe door or window H,to be closed or opened and locked. As shown in thedrawings, the door H has vertically-arranged pivots in the center, butthe said window or door may be differently hinged or pivot-ed.

On the under side of the arm E is formed a lug 1, adapted to engage oneof a series of notches J, arranged in the segment of a circle on top ofthe bracket 0. 0n the outer end of the said bracket is arranged a stopK, which limits the outward swinging movement of the arm E, whichlatter, when abutting on the said top, has moved the door or window intoa fully open position, as illustrated in Fig. 2.

On the under side of the bracket 0 are arranged similar notches J and astop K, so that the said bracket may be used on either side of thedoor-casing. The hub of the arm E is adapted to rest, when the device isin a normal position, on top of the bracket C, so

that the downward movement of the shaft is limited by the arm E.

The device is used as follows: When the door or window H is in a closedposition, as shown in Fig. 1, the lug I of the arm E abuts against theshoulder formed by the notch on the right-hand side of the bracket 0.Thus the door H is locked and opening of the door or window by pressureon the outside is prevented. When the operator desires to open the dooror window II, he takes hold of the handle D and pushes the same upwardso as to raise the shaft A a short distance, to lift the lug I above theshoulder of the bracket 0. The operator then swings the arm E totheleft, so that the shaftA is turned and the arm E, by the link F,pulls on the arm or bracket G, so that the door or window H turns on itsvertical pivots and thereby opens. When the desired position is reached,the operator drops the handle D, so that the shaft A, by its own weight,slides downward, and the lug I drops into the corresponding notch J or Jon top of the bracket 0. Thus the door or window H is locked in an openposition. When the operator desires to open the door or window fully, asshown in Fig. 2, he turns the handle D, as previously described, untilthe arm E strikes against the stop K. By then letting the shaft A drop,the lug I on the arm E engages the outermost notch.

J or J on the bracket 0, and the door is held in a fully open position,as shown in Fig 2. In order to close the door or window, the operatormoves the handle D upward to raise the shaft A, and then swings the armE to the right, so that the door orwindowHcloses, and then lets theshaft A drop, as previously described.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent- The combination of the vertically-arrangedshaft A, having handles D E, one of which has the locking-lug I, withthe semicircular brackets B and G,the latter 0 having notches EMIL HERZ.
